For a long time, it was just setting the default search provider to Google in exchange for a beefy stipend. Later, paid links in your new tab page were added. Then, a proprietary service, Pocket, was bundled into the browser - not as an addon, but a hardcoded feature. In the past few days, we’ve discovered an advertisement in the form of browser extension was sideloaded into user browsers. Whoever is leading these decisions at Mozilla needs to be stopped.

Mozilla garnered a lot of fully deserved goodwill with the most recent Firefox release, and here they are, jeopardising all that hard work. People expect this kind of nonsense from Google, Apple, or Microsoft - not Mozilla. Is it unfair to judge Mozilla much more harshly than those others? Perhaps, but that's a consequence of appealing to more demanding users when it comes to privacy and open source.
